iBasso IT01 Dynamic Driver Audiophile MMCX Detachable IEMs In-Ear Headphones with (Black)

I ordered the IT01 after reading numerous positive reviews. The in-ears are very comfortable and can easily be worn all day. I wear glasses and have no issues with the cord looping over my ears.I am enjoying the sound these put out and I find that the bass is punchier than my Tin T2 Pro's. Punchy but not overwhelming or distorted. Music sounds natural and detailed without any sibilance issues.I would by them again.

[Great sound, great build quality, and a ridiculous number of ear tips]To my untrained ear, the sound punches way above its price range. I've owned IEMs where the highs were too shrill or the bass drowned everything out. Not these. I haven't had issues with any genre.I've owned IEMs that broke with low to moderate use. Not these. My clumsy self accidentally sat on these a few times and they're still going strong. (This is actually what prompted me to write this review today)These come with a case and a lot, and I mean a lot, of ear tips (mostly silicone, a few foam). I spent maybe a week going through every single one to see what worked best for my ears. Having options is always a plus. Also, I'm not sure why they don't have pictures of the braided wire in the product pictures. It's gorgeous.I can't think of any cons at the moment, but I'll be sure to update this review if I do.Edit: The wire by the jack started fraying almost a year in, which caused the sound to cut out in both ears. Customer service was responsive and sent over a spare wire since it was under warranty.

I'm very satisfied with the sound stage, the lows, mids and highs. Vocal is a bit back(some says recessed, i don't think it is that bad). Clarity is pretty good. I don't use my big cans as often as I did before.However, as good as its stock cable is, the MMCX connection is not reliable at all. Like the other buyers has found out, they are either too loose or too tight. In my case, the right ear could easily come off. Whatever adjustments iBasso has done to fix the over tight connection, it was overdone. I'm always worried about losing it or stop working one day.Edit: 2 months into this IEMs, the right ear piece came of when it was in my pocket and was lost for good. If you have read other reviews, you know it's a common issue for the product. At the end of the day, this is a consumer but not a experimental product. From my experience, the defect design of MMCX connection make the product below consumer grade, meaning it should not be on the market until such defect is fixed.

Now this... this is an IEM worth $99. Great accessories, great cable, great sound. This is the most comfortable and well presented IEM I have heard for under $100. The tonal balance through the mids and highs is spot on and decently detailed. The bass extends pretty deep, but the quantity of the bass is a little much, especially in the 150-200 Hz range. If you can handle this with a little bit of EQ on your phone or desktop, these are hard to beat. The case they come with is really nice and convenient. They feel nice in the hand but also feel sturdy enough that I don't feel uncomfortable taking them around town with me (though I always put them back in their case when not in use).For what iBasso is trying to do here, I think they've hit a home run. High quality cable, high quality packaging, and a mostly really cohesive sound signature with elevated bass. A very easy product to recommend.

UPDATE:I'll leave it at 5 stars. Compared to what I'd used prior to this (klipsch, JBL, etc.), these are a solid choice. I ended up upgrading the MMCX cable and saw improvement. I ordered the fiio f9 pro, and ended up prefering those. I'll keep these for when I'm craving some deeper bass.Buy comply tips. Whether you buy these IEMs or not, find the correct version (500 for ibasso and fiio) and you won't look back.2019-04 initial review:Very comfortable if you're willing to find the correct fit. I would really encourage the foam and it's unfortunate more than 2 sizes were not included. While the mids and highs seem to shine through most to me, my bass forward music sounds fantastic and I'm very happy powering these off my phone.The cable has been great so far. The included case is functional and effective. Overall, I don't think you can find a better value for the price. Also a huge benefit to have mmcx for future Bluetooth upgrades or starting your audiophile collection.6/6 update: still working great. Upgraded with comply tips and a new cable and even better! Only using through Hiby R3. I'm curious how everyone is having problems with the mmcx connection. Then I read reviews about the headphones being in someone's pocket... I'm all for convenience but think you should use the headphones that came free with your phone if that's how you treat things. Feeling like most of the negative reviews just have unrealistic expectations.
